Abstract: Background Knowledge of arrhythmias in patients with end-stage renal disease (ESRD) is mainly based on ambulatory electrocardiography (ECG) studies and observations during haemodialysis (HD). We used insertable cardiac monitors (ICMs) to define the prevalence of arrhythmias, focusing on bradyarrhythmias, in ESRD patients treated with several dialysis modes including home therapies. Moreover, we assessed whether these arrhythmias were detected in baseline or ambulatory ECG recordings. Methods Seventy-one patients with a subcutaneous ICM were followed for up to 3 years. Asystole (>= 4.0 s) and bradycardia (heart rate = 4 beats) episodes, ventricular tachyarrhythmias and atrial fibrillation (AF) were collected and verified visually. A baseline ECG and a 24- to 48-h ambulatory ECG were recorded at recruitment and once a year thereafter. Results At recruitment, 44 patients were treated in in-centre HD, 12 in home HD and 15 in peritoneal dialysis. During a median follow-up of 34.4 months, 18 (25.4%) patients had either an asystolic or a bradycardic episode. The median length of each patient's longest asystole was 6.6 s and that of a bradycardia 13.5 s. Ventricular tachyarrhythmias were detected in 16 (23%) patients, and AF in 34 (51%) patients. In-centre HD and Type II diabetes were significantly more frequent among those with bradyarrhythmias, whereas no bradyarrhythmias were found in home HD. No bradyarrhythmias were evident in baseline or ambulatory ECG recordings. Conclusions Remarkably many patients with ESRD had bradycardia or asystolic episodes, but these arrhythmias were not detected by baseline or ambulatory ECG.
